"Among the items found in the graves were weapons, spurs, a bridle and a drinking horn, as well as a jet bracelet and a copper alloy belt fitting."
An as yet unidentified and empty container resembling a 'kitty box' (sic) was also found. It's use has yet to be determined but it is believed to have contained the remains of the viking's household 'pets', heretofore unknown to the western world but lovingly continued in Norse folklore.
Generations have come to know and love the "Viking Kitties".
Modern minds have, for many years, pooh-poohed the existence of such creatures ...
Magnificent though they may be.
